The Substitution Rope Story / Cartoonist Jaiko

When she was toddler, Shizuka had admired Jaian and Suneo's ability to climb trees in the mountain. Her mother does not allow her to do so, even if she wanted to. Discussing with Nobita if being someone of the different gender is better, Nobita proposes the idea of switching bodies. Doraemon lends them the Substitution Rope that allows them to do so. Nobita, now in her body, goes out to play. Embarrassed, Shizuka in Nobita's body is reluctant to go out, but Doraemon gives her the push.

Shizuka finally fulfills her wish to climb the tree in the mountain, and is delighted to see the panoramic view of the city, just like what Jaian had said. She later joins Jaian and Suneo for a baseball match, and is able to score for The Giants with her superb performance at the field.

Nobita, on the other hand, gives the impression that Shizuka has became a changed person. He finds it hard to fit with Shizuka's friends, and is tangled while skipping. Returning to Shizuka's room, he is lectured by Shizuka's mother over his etiquette.

Back home, Nobita, missing his old self, asks Shizuka to switch back his own body, but Shizuka, praised by Jaian and Suneo for her performance earlier, refuses to. Upset, he is reluctant to take a shower, but eventually gets the realization that he would be able to see his body from the inside. Meanwhile, Shizuka sees something she is not supposed to see. She almost barges in her own toilet naked, trying to prevent Nobita from taking his clothes off thus finally agreeing to switch back.
